Hi all,
after some investigation I found in pg database directory many files starting with "t". For exmple:
-rw------- 1 postgres postgres 8192 May 25 11:13 t55_16771477
-rw------- 1 postgres postgres 8192 May 25 08:12 t55_16771482
-rw------- 1 postgres postgres 8192 May 25 09:07 t55_16771614
-rw------- 1 postgres postgres 8192 May 25 08:13 t55_16771632
-rw------- 1 postgres postgres 32768 May 25 07:05 t55_16772120
-rw------- 1 postgres postgres 24576 May 25 09:04 t55_16772120_fsm
-rw------- 1 postgres postgres 8192 May 25 12:11 t55_16772129
-rw------- 1 postgres postgres 0 May 25 08:40 t55_16772131
-rw------- 1 postgres postgres 0 May 25 12:09 t55_16772285
-rw------- 1 postgres postgres 0 May 25 09:44 t55_16772293
Can this one be the reason for slow pg start?
Many thanks in advance,
Ivan.

Hi,
After stopping my pg server with pg_ctl -m immediate stop options it take hours to startup.
With vmstat I find hi pcu and io useages.
Any idea about this problem? I think it can be pg_xlog files.
How can I debug or trace this problem?
pg version is 9.4.5 running on centos 6.
Many thanks in advance.
